COMP3760/6760: Enterprise Systems Integration, XML, Web Service - IT Computer Science Assignment Help

Assignment Task

Project Brief

Provide a description on: the group meeting schedule or plan, each member’s role in the project, identifying risks and ways to manage risks, ways to communicate between members, and a log recording each meeting, discussion and dialogue between members in relation to the project. Note: all members need to contribute to the project. The description and log need to be submitted together with the four tasks.

Task 1 Collaborative Business Process and EAI

The objective of this task is

• to use BPMN notation (Week 2 lecture) to draw a collaborative business process for the GP seeing Joe’s case, in which you need to show partners (users), how they interact, and how information/messages are exchanged. In this case, the partner systems can be EHR, GP’s own medical system, hospital medical system, and patient Joe.
• There are various ways to design and implement this collaborative business process. Design and draw an EAI system that support the GP makes the inquiry to different systems and make a decision in Joe’s case.
• Explain how GP’s inquire is processed in your EAI system. You may make the necessary assumptions.

Task 2 Web Service Design

Suppose you are wrapping the components of EHR (Figure 1) as web services, which allows patients and doctors to create applications. You are required to:

• Identify the two necessary functions of these services. You can make your assumptions based on your experience in using EHR;
• For each of the above functions, identify the input/output messages;
• Use WSDL interface definition constructs to specify the above identified functions with input/output messages.

Task 3 XML Schema Design

For the above input/output messages, write their XML Schemas. You need to include the following:

• Two different ways of specifying complex types, one is defined inside the element, the other defines a complex type first, then (re-)uses it as a complex type of an element;
• Use constraints on the values of a simple typed element, on the occurrence of elements;
• Pick up one xml schema, construct a sample xml document.

Task 4 Discussion (600 words)

“The current EHR system is basically a portal for a collection of documents without proper integration”, from this description we can image the documents stored there are of different formats with different structures. For example, the hospital discharge summary is very different from diagnostic image report. The challenges is how to bring all the information together in a uniformed interface for search and query. Use what you have learned in the unit to discuss the following:

• The possible issues relating to the integration of all the components in EHR (from different layers/aspects) using examples;
• The possible technologies potentially used to support system integration at various levels/aspects;
• The options and considerations of the technologies along with their advantages and disadvantages
